Business Certainty - Mobiles

By eliminating unexpected costs and ensuring great value, the new O2 Business Certainty tariff will help you control your company's mobile expenditure during these challenging economic times.

It's a simple, easy-to-understand tariff which works on an individual basis, giving you more up-front control over the usage of each phone. This means you can concentrate on growing your business not watching your phone bills.

Now that's real peace of mind.

Not only does the tariff come with lots of inclusive minutes and texts, but it also includes certain calls on an unlimited basis, as well as built-in use of POP3 email. This means you can talk to your colleagues or customers, phone the office, text or email as much as you like - without worrying about the cost.

O2 Business Certainty also enables you to control extra chargeable services on a mobile by mobile basis, such as restricting calls to Premium Rate or overseas numbers or barring the use of the phone when abroad. In a busy working life, it's one less thing to worry about.
